FTP accounts do not work after FileZilla upgrade

This article describes a problem that occurs after you upgrade FileZilla to version 3.10, and how to resolve it.


When you try to access an account using a regular (unencrypted) FTP session after upgrading to FileZilla version 3.10, you receive the following error messages:

Error: Connection timed out
Error: Failed to retrieve directory listing
This issue does not apply to SFTP connections. SFTP connections continue to function normally in version 3.10.

If you are unsure which FileZilla version is installed on your computer, follow these steps:

  1. Start FileZilla.
  2. On the Help menu, click About.


In version 3.10, FileZilla forces TLS encryption on plain FTP connections. This applies both to new sites you create in the Site Manager, as well as any sites you have previously configured.

You can resolve this problem by resetting your accounts to use plain, unencrypted FTP connections. To do this, follow these steps:

  1. Start FileZilla.
  2. On the File menu, click Site Manager.
  3. Under Select Entry, click the site.
  4. On the General tab, in the Encryption list box, select Only use plain FTP (insecure).
  5. Click OK.
